CROSS-REFERENCE TO RELATED APPLICATION

This application is a divisional application of Ser. No. 11/359,768, filed Feb. 23, 2006.

FIELD OF THE INVENTION

The present invention is directed to a mounting bracket for an electrical box or other electrical component. The invention is particularly directed to an adjustable mounting bracket for accommodating wall cavities of different depths between opposing walls.

BACKGROUND OF THE INVENTION

Electrical boxes are commonly mounted on various mounting brackets for securing the electrical box to a wall stud or other support. The electrical boxes are dimensioned to support electrical receptacles, switches and other components and must be securely mounted to the wall stud. Many electrical boxes include a mounting bracket extending from one side of the electrical box so that only one side of the electrical box is supported by the bracket. The opposite side of the electrical box often does not include a support so that some movement of the electrical box can occur during use.

To provide support of opposite ends of the electrical box, a number of brackets have been proposed. Typically, the bracket includes a first member for attaching to a wall stud and a second member connected to the opposite side of the box so that both sides of the electrical box are supported to resist movement with respect to the wall.

One example of a prior support bracket is disclosed in U.S. Pat. No. 4,399,922 to Horsley. The bracket as disclosed includes an extension arm bent at a right angle to a plate that supports the electrical box. The plate has one side edge provided with holes for securing the plate to a wall stud. The extension arm is formed on the opposite end and has a length to contact a wall on the other side of the wall stud. The extension member includes a series of score lines that can be broken off for use with walls having different depths.

Another device is disclosed in U.S. Pat. No. 4,732,356 to Medlin. This device also includes a plate member for supporting an electrical box. The plate includes a first end portion for attaching to the wall stud and a second end portion having an L-shaped arm to contact the opposite wall. A separate extension plate is attached to the L-shaped arm to adjust the length of the arm for different depths between the walls.

U.S. Pat. No. 4,688,693 to Medlin discloses an outlet box stabilizer bracket having an extension formed at a right angle to the bracket to contact an opposing wall. The extension is cut from the bracket and bent from the bracket to form a central opening in the bracket.

U.S. Pat. No. 4,964,525 to Coffey et al. discloses an electrical box mounting bracket for connecting to a wall stud. The bracket includes a pair of side mounted support legs that are bent at a right angle from the bracket to engage the opposite wall.

Examples of other mounting brackets that contact the opposing wall are disclosed in U.S. Pat. No. 4,645,089 to Horsley, U.S. Pat. No. 4,533,060 to Medlin, U.S. Pat. No. 4,569,458 to Horsley, U.S. Pat. No. 4,572,391 to Medlin, and U.S. Pat. No. 4,603,789 to Medlin.

While the devices and brackets have been generally suitable for the intended purpose of supporting an electrical box, there is a continuing need in the industry for improved support brackets and methods of producing the brackets.

DETAILED DESCRIPTION OF THE INVENTION

The present invention is directed to a mounting bracket for an electrical box or other electrical device. In particular, the invention is directed to a mounting bracket for securing an electrical box to a wall stud and supporting the electrical box in a secure manner.

Referring to the drawings, a first embodiment of the invention is shown in FIGS. 1-6. As shown in FIG. 1, the mounting bracket 10 includes a front mounting plate 12, a support plate 14 and an extension plate 16.

Mounting bracket 10 in a preferred embodiment of the invention is formed from a single piece of sheet material having sufficient strength to support an electrical box during use. Typically, mounting bracket 10 is formed from a steel sheet that is cut, stamped or pierced to form a one piece unitary unit. As shown in FIG. 1, front mounting plate 12 has a substantially flat front face 18 and a side portion 20 offset from the front face 18 by a stepped portion 22. Side portion 20 in the embodiment shown has a substantially rectangular shape with a plurality of apertures 24 for receiving fasteners for securing mounting bracket 10 to a wall stud 26 or other support shown in FIG. 1. Front mounting plate 12 has a central opening 28 having a dimension to receive an electrical box or other electrical component. Central opening 28 defines first and second side sections 30 and 32. Top section 34 and bottom section 36 extend between side sections 30 and 32 to define the opening 28. Front face 18 includes a plurality of apertures 38 for receiving screws or other fasteners for attaching an electrical box 40 to front plate 12 as shown in FIG. 2.

Support plate 14 in the embodiment of FIGS. 1-8 extends substantially perpendicular to front plate 12 in a direction away from front face 18. Support plate 14 has a first inner section 42 connected to side section 32 of front plate 12. Support plate 14 has a second end section 44 forming an outer end 46 spaced from front plate 12.

Extension plate 16 is integrally formed with support plate 14 and is cut or stamped from support plate 14 as shown in FIG. 1. A plurality of elongated apertures 48 are pierced in support plate 14 to define a fold line 50 between support plate 14 and extension plate 16. Extension plate 16 has side edges 52 and an outer edge 54 as shown in FIG. 3. A plurality of spaced apart score lines that define fold lines 56 are formed in extension plate 16 that are substantially parallel to fold line 50. Fold lines 56 are typically formed by stamping so that portions of extension plate 16 can be folded to reduce the effective length of extension plate 16. A central opening 58 is formed in extension plate 16 by cutting or stamping. In the embodiment illustrated, a locking tab 60 is cut from central opening 58 into extension plate 16 in a direction toward fold line 50 as shown in FIG. 1. Locking tab 60 includes side edges 62 and an outer edge 64. Extension plate 16 is cut to form top and bottom sections 66 and 68, respectively, in support plate 14 that extend in a direction substantially perpendicular to front plate 12. An embossed strengthening rib 70 is formed in each top and bottom section 66 and 68 to strengthen support plate 14 and resist bending or buckling.

In use, electrical box 40 is coupled to front plate 12 and side portion 20 is attached to wall stud 26. Wall stud 26 supports a front wall 27 in phantom lines that overlies mounting bracket 10 in a conventional manner. An opposing rear wall 72 is attached to wall stud 26 on a side opposite mounting bracket 10. Referring to FIG. 2, wall stud 26 has a dimension indicated by arrow 74. Support plate 14 has a length extending from front plate 12 corresponding substantially to the dimension of wall stud 26 so that the end 46 of support plate 14 contacts wall 72 to stabilize one end of the front plate 12. Mounting bracket 10 is cantilevered from wall stud 26 by side portion 20. To prevent front plate 12 from flexing or bending in a direction toward wall 72, support plate 14 has a dimension to contact wall 72 and support mounting bracket 10.

Mounting bracket 10 is able to accommodate wall structures having different depths by selectively adjusting the effective length of support plate 14. For example, opposing wall 72 can be spaced a distance greater than the distance 74 shown in FIG. 2. Referring to FIG. 5, a wall stud 26 indicated by arrow 76 where opposing wall 72 is spaced from a front wall a distance greater than the length of support plate 14. In this embodiment, extension plate 16 is folded outwardly from support plate 14 along fold line 50 from a first position shown in FIG. 1 to a second position shown in FIG. 3 where extension plate 16 extends away from support plate 14. In the illustrated embodiment, extension plate 16 is folded flat against support plate 14 to be parallel thereto. As shown in FIG. 3, outer edge 54 of extension plate 16 is spaced from front plate 12 a distance to accommodate the depth of a wall cavity as shown in FIG. 5. As shown in the cross-section of FIG. 4, locking tab 60 is folded over the outer end 46 of support plate 14 to effectively lock extension plate 16 in an extended position with respect to support plate 14. As shown in FIG. 5, extension plate 16 effectively increases the length of support plate 14 to engage the opposing wall 72 to prevent flexing of the front plate 12 and movement of the electrical box during use.

Referring to FIG. 6, wall stud 26 can have a dimension indicated by arrow 78 that is less than the dimension 76 of wall stud 26 of FIG. 5. The wall stud 26 shown in FIG. 6 having the dimension indicated by arrow 78 forms a wall cavity having a dimension less than the combined length of support plate 14 and extension plate 16 when folded to the extended position. As shown in FIG. 6, extension plate 16 can be folded along one of the fold lines 56 to effectively shorten the length of extension plate 16 so that the folded portion of the extension plate contacts the opposing wall 72 while it supports front plate 12 in a position substantially parallel to opposing wall 72.

In the embodiment of FIGS. 1-6, mounting bracket 10 is able to accommodate wall structures having different cavity depths by folding the extension plate outwardly and where necessary folding the extension plate about the fold lines to reduce the overall length of the support plate and extension plate. In one preferred embodiment, support plate 14 has a length corresponding to the minimum depth of a standard wall structure which can be, for example, about 3.5 inches. In wall structures having a depth greater than the length of the support, the extension plate is folded outward and locked into place so that the end of the extension plate can contact the opposing wall. In the event the depth of the wall cavity is less than the combined length of the support plate and the extension plate, the effective length of the extension plate can be reduced by folding along one or more of the fold lines. The resulting tab formed by folding the extension plate along the fold line can be folded 90° as shown in the drawings or folded 180° to lay flat against the support plate or extension plate.

The locking tab as shown in the illustrated embodiment is integrally formed with the structure and folded over to clamp the extension plate in the extended position with respect to the support plate. In the illustrated embodiment, the locking tab is cut from the extension plate and positioned to fold over the outer end of the support plate. In alternative embodiments, the locking tab is formed with the support plate which can be folded over the extension plate to lock the extension plate in the extended position. In another embodiment, a separate fastener, clip or locking member can be coupled to the extension plate and/or support plate to lock the extension plate in the extended position.

In a second embodiment of the invention, a mounting bracket 90 is formed from a cut or stamped blank of sheet material as shown in FIG. 7. Mounting bracket 90 includes a front plate 92 defining a front mounting panel, a support plate 94 and an extension plate 96. As shown in FIG. 7, front plate 92, support plate 94 and extension plate 96 are integrally formed and connected together by fold lines as discussed hereinafter in greater detail.

Front plate 92 includes a front face 98 and a side portion 100 connected to front face 98 by a stepped portion 102 to offset front face 98 with respect to side portion 100. Side portion 100 includes a plurality of holes 104 for receiving fasteners to attach side portion 100 to a wall stud or other support surface. Front face 98 includes a plurality of holes 106 for receiving fasteners for coupling an electrical box to front mounting plate 92.

Support plate 94 and extension plate 96 are cut from the blank and bent outwardly from front plate 92 as shown in FIG. 9 to form a central opening 108. Central opening 108 has a dimension to accommodate the electrical box 110 and defines first and second side sections 112 and 114. A top section 116 and a bottom section 118 extend between side sections 112 and 114 as shown in FIG. 9.

Support plate 94 is connected to the inner edge 120 of central opening 108 alongside section 114. Elongated slots 122 define a fold line between side section 114 and support plate 94 as shown in FIG. 7. Support plate 94 includes a central opening 124 to define a pair of legs 126 and an outer end portion 128. Embossed ribs 130 are formed along the length of legs 126 to strengthen legs 126 during use. Outer end portion 128 has an outer edge 132.

Extension plate 96 is integrally formed with support plate 94 and coupled to outer edge 132 of extension plate 96. Elongated slots 134 are formed to define a fold line 136 between support plate 94 and extension plate 96. Extension plate 96 in this embodiment includes an end portion 138 and a pair of legs 140 extending from end portion 138. Legs 140 are cut from the blank adjacent legs 126 of support plate 94 as shown in FIG. 7. End portion 138 is connected to support plate 94 along fold line 136. End portion 138 includes an edge 140 having a locking tab 144 cut from end portion 138. Locking tab 144 is connected to end portion 138 by a fold line 146 and includes side edges 148 and an outer edge 150.

In use, mounting bracket 90 is folded to the position shown in FIG. 9 where support plate 94 is substantially perpendicular to front plate 92 and extension plate 96 is folded with respect to support plate 94 to be substantially parallel with front plate 92 and perpendicular to support plate 94. Bending support plate 94 and extension plate 96 forms central opening 108 as shown in FIG. 9 to allow the electrical box 110 to be coupled to front plate 92 and to allow access to the interior of electrical box 110. As shown in FIG. 10, side portion 100 of front plate 92 is attached to a wall stud 152 by suitable fasteners such as nails or screws. As in the previous embodiment, wall stud 152 supports a front wall (not shown) and an opposing wall 154 as shown in FIG. 10. As shown in FIG. 10, support plate 94 has a length substantially equal to the dimension of wall stud 152. In this manner, the outer edge 132 of support plate 94 and the face of extension plate 94 contact opposing wall 154 to support the end of mounting bracket 90 and prevent bending or flexing of front plate 92 with respect to side portion 100 and wall stud 152.

As in the previous embodiment, mounting bracket 90 is able to accommodate a wall cavity having different depths and dimensions. Referring to FIG. 11, extension plate 96 is folded along fold line 136 so that extension plate 96 is substantially parallel to support plate 94. As shown in FIG. 12, locking tab 144 is folded along fold line 146 over the inner edge of outer end portion 128 to secure extension plate 96 in an extended position with respect to support plate 94. As shown in FIG. 13, the combined length of support plate 94 and extension plate 96 complements the dimension of wall stud 152 so that an outer end 156 of legs 140 contact opposing wall 154 to support mounting bracket 90. As in the previous embodiment, legs 140 include a plurality of spaced-apart fold lines so that the effective length of extension plate 96 can be shortened to accommodate the dimension of the wall cavity defined by the opposing wall 154 and wall stud 152 by bending legs 140 along the selected fold line 158. The extension plate 96 is shortened in a manner similar to the previous embodiment by folding along the fold lines 158. The resulting tab can be folded to be perpendicular to the extension plate or folded parallel to the extension plate.
